Radio nondetection of the SGR 1806-20 giant flare and implications for fast radio bursts.

Abstract (from CDS):

We analyze archival data from the Parkes radio telescope, which was observing a location 35.deg6 away from SGR 1806-20 during its giant γ-ray flare of 2004 December 27. We show that no fast radio burst (FRB)-like burst counterpart was detected, and set a radio limit of 110 MJy at 1.4 GHz, including the estimated 70 dB suppression of the signal due to its location in the far sidelobe of Parkes and the predicted scattering from the interstellar medium. The upper limit for the ratio of magnetar giant flare radio to γ-ray fluence is η_SGR <= 10^7 Jy ms erg^-1 cm^2. Based on the nondetection of a short and prompt γ-ray counterpart of 15 FRBs in γ-ray transient monitors, we set a lower limit on the fluence ratios of FRBs to be η_FRB >= 10^7-9 Jy ms erg^-1 cm^2. The fluence ratio limit for SGR 1806-20 is inconsistent with all but one of the 15 FRBs. We discuss possible variations in the magnetar-FRB emission mechanism and observational caveats that may reconcile the theory with observations.
